She made her own tacos once (using the commercially available taco shells) but never repeated it ever again. The mix she made was awesome but there was a problem with the taco shells. The shells are crispy. It crumbles upon bite and the fillings start falling down to a mess. The best way of eating is placing it on plate and using spoon and fork. So the taco shells are of no use. Just a crispy decoration.
So these few pieces of taco shells has been staying near the vegetable bin for quite a while. Throwing it away is an option but it would put some hard earned money to waste.
The taco shells are still crunchy. The cold storage condition has maintained its crispiness. It could be eaten as is. However, it is plain and has a strong taste of raw flour. I tried dipping it in mayonnaise and soaking a bit in chili hot vinegar.
